Special Issue Information

Dear Colleagues,

The integration of renewable energies into modern electrical systems has steadily increased in recent years, with the aim of reducing the use of fossil fuels and the environmental impact. However, the uncertainty in the generation of these energies can cause instability in the electrical grid. Therefore, it has been proven that energy storage systems (ESSs) represent a significant solution to ensure the continuity of electrical services in distributed generation systems. ESSs are essential for energy storage, in times of excessive generation, and for releasing it when required. For this reason, the integration of microgrids and smart grids with energy management models have received attention as viable and promising solutions. On the other hand, optimization and intelligent systems increasingly involve new challenges in electrical grids. The optimal management of energy storage systems, intelligent electrical systems, stability in electrical systems, modern control strategies, resilient electrical systems, and configuration for off-grid systems are some of the potential drawbacks, instigating the analysis of new methods and strategies to improve current productivity and energy distribution.

These contributions will not only promote improvements in the quality of electricity supply, but will also facilitate the transition towards a more sustainable and efficient energy scenario.

This study explores the feasibility of using impedance relays in electrical distribution systems, a context where their application is not as common as in transmission systems. Given the dynamic nature and complex topology of medium-voltage distribution systems, this work proposes an innovative methodology integrating clustering algorithms and metaheuristic techniques to optimize the placement of impedance relays and enhance system reliability and resilience. Using CYME simulation and the Ant Colony Optimization (ACO) method, case studies were designed to validate the effectiveness of the proposed methodology. The results demonstrated that strategic placement of impedance relays reduces failure frequency and significantly improves the system’s response to such failures. This approach allows for a more efficient configuration and quicker response, which is crucial for maintaining continuity and quality of power supply. A detailed analysis of system behavior under various fault scenarios illustrates the robustness and adaptability of the proposed solution, marking a significant advancement in the protection and optimization of electrical distribution systems.
